`VIBRATINe-CYLINolan ENGINE.

SPECIFICATION forming part of Letters Patent No. 348,097, dated August 24, 1886.

Application llled May 22, 1886. Serial No. 203.045.

To all whom, it may concern: I

Be it known that I, JOHN S. BARDEN, of Warren, in the county of Bristol and State of Rhode Island, have invented anew and useful Improvement in Vibiating-Oylinder Engines, of which the following is a specification.

My invention relates to that class ofengines in which the cylinder is pivoted at one end upon a stationary valve, so as to vibrate with the movement of the crank; and it consists inV the improved means forholding the vibrating cylinder against the curved surface of the stationary valve, as hereinafter fully set forth.

Figure l is a vertical section taken in the line x x of Fig. 2, showing a vertical section of one of the cylinders of a three-cylinder envgine, and the relative position of the other two cylinders in elevation. Fig. 2 is apartial top view showing one of the cylinders in position, the other` two cylinders being removed from the stationary valve. Fig. 3 is a partial side elevation of Fig. 2.

In the accompanying drawings, A A A are the cylinders of a three-cylinder engine, by

u. means of which a continuous rotary movement is produced.

The shaft B is provided with the cranks a a a, and is held in the boxes s of the bearingstandards C O.

The stationary valve D, made in segment form, is provided with a central partition, b, which divides the interior of the valve into two parallel chambers, E and F, one of which may be used for the inlet of steam or other fluid and the other for the exhaust of the same.

The valve-ports c and d, which are to be either ring p. rlhe face-plate G is hollowed on its face to fit the periphery of the stationary valve (No model.)

D, and is prevented from rotation with respeet tothe piston G and the valve D by means 5o of the piu q, which is fixed in the face of the piston G and loosely enters the hole r in the back side of the face-plate G.

The piston G is secured to the crank a by means of the split box H, the split shank o of which is screwed into a threaded perforation at the outer end of the hollow piston-rod u, and the s lit box H is prevented from turning with respect to the position of the piston G and its hollowed face-plate G by means of 6o the penetrating set-screw 10.

The inlet-pipe H connects by a two-way cock, e, with the pipes li lz, leading to the chambers E and F, respectively, and the exhaust-pipe I is connected by a two-way cock, f, with the pipes i' t', leading from the chambers E and F, and by means of the two-way cocks@ andf the steam or other operating fluid may be directed into either of the chambers of the valve, as desired, so that a reverse 7o movement can be therebyimparted Ato the shaft B.

The stationary valve D is made in semicircular or segmental form, to fit the circular seat g at the lower end of the cylinder A, and to i the ears j j at the lower end of the cylinder is secured the yoke-piece J by means of the screws k 7s, and at the center of the yokepiece J is placed the bearing-head K, which may be either fixedly attached to the yoke J 8o or form a part thereof; or the bearing-head K may form the head of a cylindrical bolt, L, which is held against the center point of the semicircular valve D by means of the spiral spring Z and hollow Screw m.' The cylinder 85 A will thus be held to its seat upon the stationary valve D by the adjustable springpressure of the head K against the center line of the outer side of the semicircular valve D.

The bearing-head may be made in conical go pointed form or in the form of a knife-edge, or it may be rounded, as preferred.

I claim as my invention- Y l. The combination of the segmental stationary valve, the vibrating cylinder, the rigid yoke secured to the vibrating cylinder,

the centrally-located bearing-head adjustably rocating piston hollowed on its face in conheldin the yoke, the spring, and the adjustformity to the curvature ofthe face of the lo ing-screw for the bearing-head, substantially stationary valve, substantially as described.
